+ * # MCP Kotlin SDK
+ *
+ * A Kotlin Multiplatform implementation of the Model Context Protocol (MCP).
+ *
+ * This is the main SDK module that provides a convenient single dependency
+ * for all MCP functionality including:
+ *
+ * - Core protocol types and utilities ([kotlin-sdk-core])
+ * - Client implementations ([kotlin-sdk-client])
+ * - Server implementations ([kotlin-sdk-server])
+ *
+ * ## Usage
+ *
+ * Add this dependency to your project to get access to all MCP Kotlin SDK functionality:
+ *
+ * ```kotlin
+ * implementation("io.modelcontextprotocol:kotlin-sdk:$version")
+ * ```
+ *
+ * This will transitively include all core, client, and server components.
